Genuine Cadillac Deville Ignition Control Module

The Ignition Control Module for Cadillac Deville switches the coil current on and off. It does this so that the spark can happen at just the right time for smooth power and low emissions. The Ignition Control Module reads a pickup in distributor systems or a crank sensor in distributorless systems and rapidly grounds then ungrounds the coil primary circuit to collapse the field and send up to 40,000 volts to the plugs. The early types are located inside the electronic distributor with centrifugal and vacuum advance. Later, the modules fitted to mid-1990s Cadillac Deville motor cars linked with the engine computer that set timing from crank speed, load, and knock data. The aim of both versions is similar, but the distributor unit controlled primary flow in the first version while the newer solid state design reports status back to the computer, allowing an automatic advance and eliminating mechanical wear points. When the Ignition Control Module fails, spark stops. Therefore, diagnosis starts by checking for battery voltage at the coil and looking for flickering on the negative side with a test light. When the voltage appears to be steady instead of blinking, the Ignition Control Module is likely the culprit. However, wires or sensor gaps may also be at fault. Owners of modern Cadillac Deville like the later Ignition Control Module because its faster transistor switching generates hotter spark, which helps deliver better fuel economy.
